Question

The following are characteristics of which motor theory?

A. Movement is activated by sensory stimuli or central processes
B. One can remove the afferent input, but still have a patterned motor response
C. More flexible than the concept of reflex because it can be activated by either the sensory stimuli or by central processes
D. View the CNS as more about the physiology of actions rather than reactions

Answer 1

The theory described is related to motor control, emphasizing both sensory-driven and central CNS processes in initiating movement, representing a shift from simple reflexive actions to a more complex understanding of the physiology of actions.

Step-by-step explanation:

The characteristics described in the question pertain to a theory of motor control that sees actions as being initiated not just as reactions to sensory stimuli but also through central processes in the Central Nervous System (CNS). Movement can be sensory driven or centrally orchestrated, highlighting the flexibility and complexity of the motor system beyond simple reflexes. This perspective acknowledges the important role of CNS regions, such as the cerebral cortex and brain stem, in the integration of sensory inputs and the formulation of motor responses. Instead of viewing movement as merely a consequence of reflexive mechanisms, this approach considers the CNS as actively involved in the physiology of actions, suggesting a more sophisticated regulatory role in motor function.
